what's the difference between pastoral rangeland and cultivated land?

Question

this is all to do with desertification in the Sahel, Africa

Answer 1

Pastoral [pasture] rangeland [roaming land] - land that cattle or other livestock have used for grazing. Grazing is eating and moving along as you eat up all of the food material [usually plants] or run out of water or weather turns bad. North American example: cowboys herded cattle on the trail from Texas to Chicago.
Cultivated land - land that has been tilled, plowed, planted or otherwise "farmed". North American example: the wide, open prairie fields of the Midwest were transformed into the world"s bread bowl.
Both are ways that humans have changed the land to feed themselves and the rest of the world.
Neither good nor bad.

Answer 2

pastoral rangeland is land animals use to range. it's covered in grass and weeds that the animals can eat.
culitvated land means humans have been working on it. the grass has been all plowed up and the soil has been tilled, ready for planting crops.
